SPECIFICATION forming part of Letters Patent No. 710,524, dated October7, 1902.

Application filed January 22, 1900. Serial No. 2,405. (No model.)

To all whom it may concern.-

Be it known that I, GORDON JOHN Soorr, a citizen of the United States,residing in the city and county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inCoupling Devices, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification.

The object of this invention is to provide a simple and efficientcoupling device whereby two rotatable members may be operativelyconnected in a manner to permit and insure their positive and concertedrotation at a uniform rate of speed irrespective of the angles or planeswithin limits that they may occupy or be caused to assume in respect toeach other. The said members may be formed on or secured to independentshafts to afford a union therefor, one of which shafts maybe a drivingfactor and the other be driven thereby, the interposed couplingpermitting either or both shafts to be simultaneously or independentlyadjusted to different planes or angles without interrupting or affectingthe cooperation of the shafts. The invention is therefore especially,though not exclusively, useful in connection with mechanism wherein thedriving-shaft is rigidly supported and the driven shaft is mounted uponan oscillating frame or support or with constructions wherein prescribedadjustments of the driven shaft are required during its positiverotation.

Accordingly the invention, as generally stated, comprises two membershaving a positive yet yielding interlocking connection.

It also comprises novel features of construction, which will behereinafter particularly described and claimed.

In the annexed drawings, which illustrate one form of my invention,Figure 1 is a sectional elevation of the device as applied to twoshafts. Fig. 2 is an end View thereof. Fig. 3 is a transverse verticalsection on the line 3 3 of Fig. 1. Fig. 4: is a similar section showingthe two members as moved oneeighth of a revolution.

A B represent two rotatable members, the former of which is adapted tobe rotated from a suitable source of power and the other to be rotatedby the first or driving member, or the converse. In the present instancethese members comprise heads or disks, one, A, of which is provided nearits periphery with a series of lateral projections a and the other witha corresponding series of spaces or orifices Z), preferably circular inform, into which said projections extend. These spaces or oriiices arelarger in diameter than the projections and are so disposed relativelythereto that the projections simultaneously and continuously bearagainst the opposing parts of the member B irrespective of its positionof adjustment within defined limits. Hence if the member A be rotatedthe projections thereon bearing against the member B will positively anduniformly revolve the latter, and this whether the member B be parallelwith or inclined relatively to the member A.

It will be understood, of course, that the relative diameters of theprojections and the spaces or orifices determine the extent of possiblerelative adjustment of the two members.

'In the present instance the members A and B are represented as mountedupon the adja cent ends of two shafts A B, respectively, which arecoupled thereby. These shafts have their hearings in suitably-supportedboxes at b, respectively. The bearing for shaft B comprises an eccentricbushing 6 by the adjustment of which said shaft may be set in differenthorizontal planes. The bushing is provided with a worm-wheel b withwhich gears a worm b on a spindle If, by the rotation of which minuteadjustment of the eccentric hearing may be eifected.

The means just described for supporting and adjusting the shaft 13' isused for illustration only.

From the foregoing it will be seen that if the plane or angle of theshaft 13 be changed or adjusted while the other or driving shaft A is inoperation an unremitting circular motion will beimparted to the formershaft, owing to the uninterrupted action of the projections to withinthe spaces or orifices of the member B. It will also be seen that if theeccentric bearing for shaft B be continuously rotated or reciprocatedsaid shaft will be caused to rise and fall without impairing ordisconcerting its speed of rotation derived from the shaft A.

I claim as my invention 1. In a coupling device for relatively movableor adjustable parts, two rotatable members one of which is provided witha lateral projection and the other with acircularspace into which saidprojection extends, said space being of greater width or diameter thanthe projection, whereby said members may be relatively adjusted inparallelism with each other and the projection will at all times coactwith the wall of said space, substantially as described.

2. In a coupling device for relatively movable or adjustable parts, tworotatable members with their opposing faces out of contact with eachother, one of which is provided with a series of lateral projections andthe other with a corresponding series of circular spaces into which saidprojections extend,said spaces being of greater width or diameter thanthe projections, whereby said members may be relatively adjusted inparallelism with each other and the projections will at all times coactwith the walls of said space, substantially as described.

3. In a coupling device for relatively movable or adjustable parts, tworotatable members, one of which is provided with a series oflateralprojections and the other with a corresponding series of circular spacesor orifices in to which said projections extend,said spaces l ororifices being of greater diameter than the projections, whereby saidmembers may be relatively adjusted in parallelism with each other andthe projections will at all times coact with the walls of said space,substantially as described.

4. In a coupling device, the combination with two shafts, and means forchanging their relative positions, of rotatable members on the adjacentends of said shafts, one of which membersis provided with a lateralprojection, and the other with a space into which said projectionextends,said space being of greater width or diameter than theprojection, substantially as described.

5. In a coupling device, the combination with two shafts, and means forchanging their relative positions, of rotatable members on the adjacentends of said shafts, one of which members is provided with a series oflateral projections and the other with a corresponding series of spacesinto which said projections extend, said spaces being of greater widthor diameter than the projections, substantialiy as described.

In testimony whereof I have hereunto atfixed my signature in thepresence of two subscribing witnesses.

GORDON JOHN SCOTT.
